BEVERAGE GAS CHARGING APPARATUS Filed Feb. 10, 1931 Patented Apr. 19,1932 PATENT OFFICE ANTHONY W. MORRIS, OF SPOKANE, WASHINGTON BEVERAGEGAS CHARGING APPARATUS Application filed February 10, 1931. Serial No.514,891.

invention relates to beverage gas charging apparatus and certain objectsof the invention are to provide an apparatus for charging beverages withgas that is adapted is for home or store use and which embodies meansfor supplying the gas from a commercially filled gas tank to the wateror other liquid in predetermined increments as desired, means wherebythe gas supply is automatically cut oil and turned on by its own forceupon reaching a predetermined pressure, means whereby the force of thecharging or incoming gas is utilized for causing a thorough agitation ofthe water whereby a complete mixture of the gas therewith is effected,and means whereby the water may be manually agitated to cause a thoroughmixture of the gas therewith.

With the above and other objects in view which will appear as thedescription proceeds, the invention consists of the novel con:struction, adaptation, combination and arrangement of parts hereinafterdescribed and claimed. These objects are accomplished by devicesillustrated in the accompanying drawings; wherein Figure 1 is a view infront elevtion of the assembled device;

a F ig. 2 is a top plan view of the same;

Fig. 3 is a view in central vertical section of the water tank showingthe agitating means;

Fig. 4 is a fragmentary view in vertical section showing the pressurevalve for automatically controlling the gas supply;

Fig. 5 is a fragmentary view in elevation showing a gas tank installedin its retainer casing;

Fig. 6 is a view in horizontal section taken substantially on a brokenline 6, 6 of Fig. 3 and showing the automatic agitation means; and vFig. 7 is a detail view in central vertical section of the gas chargingvalve means.

Referring to the drawings throughout which like reference numeralsindicate like parts, the numeral 5 designates a housing of any desiredornamental design. Said hous ing has a cylindrical upstanding retainercasing 6 mounted on one side thereof that is adapted to receive andretain a gas tank 7 as shown in detail in Fig. 5 of the drawings. Saidgastanks are supplied to the trade or home already filled withcarbonated gas or the like under pressure as will be understood.

From the tank 7 the gas, under pressure, is

allowed to escape by means of a cock 8 connected to a pipe 9. The remoteend of said pipe is connected to a cylindrical valve casing 10; shown indetail in Fig. 7, and containing means whereby the passage of the gastherethrough may be controlled. A partition 11 divides said casing intoa relatively large entry compartment 12 and a relatively small adischarge compartment 13. A valve stem 14 slidably disposed through thefront wall of the'housing 5, through the partition 11 and through aspider guide 15 within the valve casing, has a pointed end 16 that isadapted to engage a seat at the point of entry of said pipe into thecasing' A cut-01f valve 17is provided at said partition and a spring 18for the valve stem normally retain said valve in the closed position andthe pointed end of the valve stem in the open position as shown. Theexterior end of said stem is provided with a knob 19 and at each timepressure is applied to said knob the pointed stem end will close theentry port to the valve casing and the cut-01f valve 17 will be opened.Thus the gas within the large compartment 12 will pass into thedischarge compartment 13 and then outwardly through a pipe 20.

The pipe 20 conveys the gas into the bottom portion of a water tank 21through a round valve 22 that is provided with a partition 23 having apassage 24 therethrough as most clearly shown in Fig. 4c of thedrawings. An upstanding valve stem 25 passes slidably into said roundvalve and its pointed end is adapted to close said passage. The upperend portion of said stem is slidably disposed through a smallcylindrical casing 26 secured against the upper wall portion of thewater tank. A piston 27 is fixed to the upper end of the valve stem andis slidably and snugly disposed within said casing. A spring 28, withinthe casing, is adapted to normally retain said piston in the upward orraised position and the lower pointed end of the valve stem away fromits seat thus allowing the gas to pass through the valve 22 and throughits nozzle 29 into the water within said water tank. When the gassuiiiciently charges the water within said tank and its pressure reachesa predetermined point its pressure force will overcome the resistance ofthe spring and press the piston 27 downward causing its stem 25 to closethe valve passage 2a and prevent, for the. time being, any more gas fromentering said water tank. As the charged water is drawn oft from thetank the pressure therein will drop to a point that is less than theforce of the spring 28, which will again cause the valve to open andpermit more gasto enter the water tank as will be understood.

The nozzle 29 of the valve 22 discharges into a small housing 30 fixedcentrally within the bottom of the water tank 21 and having a pluralityofopenings, 31 spaced around its bottom whereby the gas mayescape andspread out into'the water w'thin said tank. A; stub-shaft 32 isrevolubly mounted in said housing and projects upwardly therethrough andpropeller or fan blades 33 are secured thereto within the housing. Theupper eX- terio-r end portion 3a of "said stub-shaft is square in crosssection and the lower-enlarged end portion 35 of a; relatively longshaft 36- is providedwith a hollow recess that is also square in crosssection and which slidably receives the projecting end of thestub-shaft.Caaid long shaft extends upwardly-through a packing gland 3-? centrallydisposed in the top seer the water tank which is threadedly installedand may be readily removed for the purpose ofsujaplying fresh water tothe tank, and a plurality'of'paddle blades 39. are keyed in spacedrelation to said long shaft in alternate. vertical and horizontal''disposition as shown in Fig. 3; p

Referring to Fig. 6 of the drawings, it willfbe noted that the nozzle 29is arranged to cause the gas discharged; from the pipe'20 to strike-thepropeller, blades 33-at a tangent thus revolying said blades togetherwith the shaft and its paddle blades 39, Therotary motion of said paddleblades will thoroughly agitate the water within the tank 21; and thuscause a completemixture off the incoming gas therewith. The water,within said tank mayalsobe manually agitated, by means of a knobAdontheunper, exterior endofi the long shaft whereby saidshaft may berotated. At the samev time said, shaft may be. moved p and own by: h sas nlarg d s c endportio n35 slidesonithe square stub-shaft portion, 8%,thus. increasing the agitation; of the water. Eh stop member, 4E1 isfixed to .said long shaft and, engages the top 38a Of! the water-tanktopreventthe socket end; shaft portion from being disengaged {from thestubshaft. The charged waterisclrawn ofi from the water tank through apipe 42 and discharges through a delivery faucet 4:3.

It will now be apparent that I have provided a beverage "as chargingapparatus comprising means I01 supplying gas to the beverage inpredetermined amounts, means whereby the gas supply is automatically cut0E and turned on by its own pressure, automatic means whereby the forceof the gas is used to agitate the beverage and cause the gas to be morethoroughly mixed therewith, and means whereby the automatic agitatingmeans may be manually operated.

Having thus described my invention, it being understood that minorchanges may be resorted to in its construction and arrangement withoutdeparting from the scope and spiritof the invention, what. 1 claim andde sireto secure by Letters Patent of the United States is :--o
